• What Women's Shoe Width Measurements Mean Shoe manufacturers have standardized rules for how to measure length but shoe width measurements are much more variable. There is some general agreement that a shoe increases 3/16th of an inch around the circumference of the ball of the foot for every increase in width for the same length.||Here are the terms used to measure shoe widths moving from the most narrow to the widest: ||AA = N = "narrow" or "double A" ||M = B = "medium", the most common or "average" width for that size. ||W = C = "wide"
